Rather than face a life underground, the Kastrians chose, what Rokon called, "final oblivion". They also had the race bank destroyed so that, if Eldrad returned, he could not restore the species from there and wage war as their king. Rokon created recordings of himself imparting this information which Eldrad saw when he returned to Kastria one hundred and fifty million years later. He found Rokon's body and considered himself cheated of his destiny - to overthrow the king. (TV: The Hand of Fear)
